Can Cause Death, Serious Injury, or Property Damage. Please take note of our latest information. Systems with safety-related characteristics are subject to special operational safety requirements on the part of the operator. The supplier is also obliged to comply with certain actions when monitoring the product. For this reason, we publish a special newsletter containing information on product developments and features that are (or could be) relevant to operation of safety-related systems. By subscribing to the appropriate newsletter, you will ensure that you are always up-to-date and able to make changes to your system, when necessary: SIEMENS Newsletter (http://www.siemens.com/industrial-controls/newsletter) Register for the Newsletter by checking the appropriate box: * Controls and Distribution News Safety notices NOTICE Observe the ESD guidelines When handling and installing the devices, observe the ESD guidelines. Connection is only permitted when the power adapters have been deactivated. 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 9 Introduction 1.6 Product-specific information ESD guidelines ESD components are destroyed by voltage and energy far below the limits of human perception. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged. ESD components which have been subject to such voltage are usually not recognized immediately as being defective, because the malfunction does not occur until after a longer period of operation. NOTICE Damage to the speed monitor from electrostatic charging! The speed monitor contains electrostatically sensitive devices. These modules will be destroyed or damaged by improper handling. * You must discharge your body electrostatically immediately before touching an electronic component. To do this, touch a conductive, grounded object, e.g., a bare metal part of a switch cabinet or the water pipe. * Always hold the component by the plastic enclosure. * Electronic modules should not be brought into contact with electrically insulating materials such as plastic film, plastic parts, insulating table supports or clothing made of synthetic fibers. * Always place electrostatic sensitive devices on conductive bases. * Always store and transport electronic modules or components in ESD-safe conductive packaging, e.g. metallized plastic or metal containers. Leave the component in its packaging until installation. Note In the case of capacitive or inductive load at the output contacts, sufficient suppressor circuits must be provided to protect against contact overload. A fuse must also be connected in series to protect against welding of the safety contacts (see Chapter "Technical data (Page 65)"). Note Routing of the sensor cables If EMC interference is to be expected, all initiator/encoder cables are to be shielded when laid. The shielding must be connected to PE at both ends. 3TK2810-1 safety-related speed monitor 10 Manual, 05/2014, NEB926246402000/RS-AC/005 Introduction 1.6 Product-specific information Intended use WARNING Intended use Can Cause Death, Serious Injury, or Property Damage. The devices may only be used for the applications described in the catalog and the technical description (see Chapter "Application (Page 16)"), and only in conjunction with equipment or components from other manufacturers which have been approved or recommended by Siemens. You must also ensure that suitable and reliable sensors are used (see Chapter "Basic versions (Page 17)" and "Configuring (Page 50)"). This product can function correctly and reliably only if it is transported, stored, assembled, and mounted correctly, and operated and maintained as recommended. Before you run any sample programs or programs that you have written yourself, make sure that running the plant cannot cause injury to anyone else or damage to the machine itself. EU notice: Start-up/commissioning is absolutely prohibited until it has been ensured that the machine in which the component described here is to be installed fulfills the regulations/specifications of Machinery Directive 2006/42/EC. Dormant error detection Note In the case of longer standstill times (t>= 24hrs), forced dormant error detection must be carried out before restarting the system (function test of the application). Exception: This forced dormant error detection procedure is not necessary when using NAMUR sensors. Connection of the initiators Note If common sensor potentials are directly connected to the initiators and a common return wire is connected to the 3TK2810-1 device, the first error that occurs will result in a loss of the safety function. Thus the maximum achievable SIL = 1 and the PL = c. A series connection of proximity switches is not permitted. 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 11 Introduction 1.6 Product-specific information Encoder NOTICE Use of encoders In order to achieve the highest possible SIL / PL when using encoders, 2-channel encoders (4 tracks: A, A/, B, B/) with defined failure responses (high-resistance outputs > 170 kOhm) must be used. If such information cannot be found on the encoder manufacturer's data sheet, then the failure response data must be requested from the encoder manfuacturer. No specific safety encoders have to be used on the 3TK2810-1 safety-related speed monitor. If an encoder is used, the encoder's FIT value (Failure in Time) must be incorporated into the calculation of the safety chain. Encoders that are operated on a 3TK2810-1 safety-related speed monitor must have the following properties: TTL/HTL encoders that provide two signal tracks with the respectively inverted signals. All sin/cos encoders that supply both the sine and the cosine tracks with the respectively inverted signals (sin, /sin and cos, /cos). The phase offset of the two signals A (or sin) and B (or cos) must be 90 , between A and /A or B and /B it must be 180 in each case. The encoder's signals must have a high resistance in the event of failure. In other words: the corresponding track must supply a resistance of at least 170 kOhm. The 3TK2810-1 speed monitor detects a disrupting offset of the signal track or mutual overtaking of the signals in the case of sin/cos encoders. Detection of the fault is independent of the set frequency. The 3TK2810-1 safety-related speed monitor assumes the safe state and issues a fault message. It is the responsibility of the user to check whether a specific encoder and its pin assignments match the 3TK2810-1 safety-related speed monitor. 3TK2810-1 safety-related speed monitor 12 Manual, 05/2014, NEB926246402000/RS-AC/005 Introduction 1.6 Product-specific information Actuator wiring up to PL e / Cat. 4 per ISO 13849-1, or SILCL 3 per IEC 62061 Figure 1-1 Dual-channel actuator wiring via two terminals Figure 1-2 Dual-channel actuator wiring via one terminal Note To achieve SILCL 2/3 as per IEC 62061 or PL d/e as per EN ISO 13849-1, a fault exclusion such as a short-circuit to P or M is required. This can, for example, be implemented within a control cabinet or by installing the connection cables in such a way that they are protected. If this is not possible, the actuators must be wired via two safety-related outputs, see image "Dual-channel actuator wiring via two terminals". For this purpose, separate cables must be laid to actuators / contactors. 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 13 Introduction 1.6 Product-specific information 3TK2810-1 safety-related speed monitor 14 Manual, 05/2014, NEB926246402000/RS-AC/005 Product description 2.1 2 Overview All key product features at a glance General information: TUV approval / UL approval - Suitable for use in applications to Level (SIL) 3 in accordance with IEC 61508 - SIL claim limit (SIL CL) 3 in accordance with IEC 62061 - Performance Level (PL) e in accordance with EN ISO 13849-1 - in accordance with EN 60204 Width 45 mm Frequencies from 1Hz to 400 kHz can be monitored depending on the sensor used.

Standstill permanently enabled. Autostart/monitored start LED displays for status diagnostics Display for status diagnostics and device parameterization Installation conditions: The devices must be installed in control cabinets with degree of protection IP54 or higher, taking account of the ambient conditions. 2.2 Application The device is designed for use on machines and plants whose motions or moving parts can constitute a hazard to personnel or machinery. The device continuously carries out standstill monitoring (output circuit 13/14) and speed monitoring (output circuit 23/24). For speed monitoring, there is a choice between automatic and setup mode. With the corresponding circuitry and suitable additional components (such as drives, sensors and tripping elements), the 3TK2810-1 can be used to implement the safety functions STO (safe torque off), SOS (safe operating stop), SLS (safely limited speed), and SSM (safe speed monitor) from the EN 61800-5-2 standard. Note Routing of the sensor cables If EMC interference is to be expected, all initiator/encoder cables are to be shielded when laid. The shielding must be connected to PE at both ends. 3TK2810-1 safety-related speed monitor 16 Manual, 05/2014, NEB926246402000/RS-AC/005 Product description 2.3 Basic versions 2.3 Basic versions 3TK2810-1 speed monitor The speed monitor is the main component of safety-related speed monitoring and is necessary in every application. The terminals and the RJ45 interface are used for the outputs, and for supplying the device with power and signals. The device is parameterized using the keys and the display. The LEDs and the display show operating statuses, error messages and diagnostics data. The device can be configured via the display and the keys on the front panel or via RJ45 with an appropriate connecting cable (see Chapter "Accessories (Page 23)") by means of the copy function. The speed can be detected by the following measuring sensors: Two NPN or PNP proximity switches (design versions with NAMUR sensors) connected to inputs E1 and E2. The proximity switches (NAMUR sensors) are supplied with 24 V DC by the speed monitor at terminal U (design version NAMUR 8.2 V DC at terminal U1 and U2). Encoders (sin/cos, TTL, HTL) connected via cable adapters (available as accessories) to the RJ45 interface. The encoder is not supplied with power by the speed monitor. Absence of feedback must be observed. When selecting the encoders it must be ensured that the signal tracks A, B and their inverted tracks are present. A combination of encoder and proximity switch (or in the case of NAMUR sensor version). 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 17 Product description 2.3 Basic versions Functional principle of the 3TK2810-1 speed monitor The 3TK2810-1 speed monitor is used for safety-related detection or monitoring of a standstill (output 13/14), and additionally for monitoring a set speed window (lower and upper speed limit) in setup or automatic mode (output 23/24). To detect the standstill or the speed of the motor, the speed (frequency) is measured using two NPN or PNP proximity switches (design version with NAMUR sensors) or using encoders (sin/cos, TTL, HTL) with two signal tracks and their inverted tracks. (See Fig. "Example of HTL level signal characteristics") Figure 2-1 Example of HTL level signal characteristics A combination of encoder and NPN or PNP proximity switch / Namur sensor is also possible. Evaluation is carried out in two diversely redundant microcontrollers using the applied pulse trains. The measured frequency is compared here with the specified speed limit for standstill, and with the limits for setup or automatic mode (depending on the operating mode). The speed limits for the individual operating modes can be adjusted by the user to optimally adapt the speed monitor to the most diverse applications and motor types. If a motor standstill is detected, NO contact paths 13/14 are connected. If the speed is within the specified limits of setup or automatic mode, NO contact paths 23/24 are connected. Power-up/self-test Once the power supply has been applied, the device performs a self-test. During the self-test phase, all LEDs briefly light up (lamp test) and all the pixels on the display are energized for approximately 2 seconds. After power-up, the LEDs light up according to the device status. 3TK2810-1 safety-related speed monitor 18 Manual, 05/2014, NEB926246402000/RS-AC/005 Product description 2.3 Basic versions Functional principle in setup mode If the 3TK2810-1 safety-related speed monitor is switched to the setup mode (control of terminal EA1), the output contact 13/14 closes immediately. If the machine speed is also within the parameterized speed window, the output contact 23/24 closes. If setup mode (control of terminal EA1) is selected, monitoring of the protective door contacts is deactivated (sensor circuits T1/P1 and T2/P2). The protective door can now be opened by an enabling command to the interlock magnets.

Signaling outputs 15 and 25 The semiconductor signal outputs 15 and 25 are designed, for example, for connection to a PLC and not for use in safety-related functions. They function as follows: The internal supply potential (URel approx. 24 V) is output via terminal 15 when the speed drops below the set standstill speed (n < nStill), in other words, if standstill is detected. The internal supply potential (URel approx. 24 V) is output via terminal 25 if the speed is within the set speed limits of setup and automatic mode (nmin < n < nmax). 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 25 Functions 3.1 Terminals and their functions Test signals T1, T2, T3, T4 To detect errors in the input circuit or in processing of the safety-related inputs ST, RF1, RF2, EA1, EA2, P1, P2 and MAG, a dynamic output signal is routed via the contact blocks, and via the start and feedback circuits. The output signals at the individual outputs T1, T2, T3 and T4 vary here so that cross-circuits between the output signals can thus also be detected. Signal input ST (start circuit) The start signal is applied at this input. ST is supplied by test signal T4. To start the motion connected at 23/24 as well as the monitor, the on pushbutton must be pressed in the case of manual start. The pushbutton is monitored for cross-circuit or short-circuit by scanning the falling edge (opening of the on pushbutton) at switch-on. For this reason, it must not be pressed for longer than 3 s. If a cross-circuit or short-circuit is detected, the device switches to the safe state and a diagnostics message is displayed. After correction of the fault, it is necessary to perform a reset (see Chapter "Troubleshooting (Page 57)") or a restart by switching the supply voltage off and on. At autostart, the test signal T4 must be applied at ST to start the device using a jumper. Signal input MAG (interlock for protective door) MAG is supplied by test signal T4. When the hazardous motion is started (output 23/24), the protective door must be interlocked. The interlock magnet is equipped with a contact that is read into the device via the MAG terminal. If the contact is closed, the device cannot be started or it goes immediately to a safe state (output contact 23/24 drops out). However, as soon as the contact is closed again, the device can be restarted. Acknowledgment of the error is not necessary. The contact is permanently monitored. If this is not used, terminals T4 and MAG must be jumpered. Signal input RF1 (feedback circuit for setup or automatic mode) RF1 is supplied by test signal T3. The NC contacts of the external contactors connected at terminal 24 are read in via terminal RF1. Connection of output contact 23/24 is only possible if the feedback contacts are closed. If contact extension or reinforcement is not used, terminals T3 and RF1 must be jumpered. 3TK2810-1 safety-related speed monitor 26 Manual, 05/2014, NEB926246402000/RS-AC/005 Functions 3.1 Terminals and their functions Signal input RF2 (feedback circuit for standstill) RF2 is supplied by test signal T3. The NC contacts of the external contactors connected at terminal 14 are read in via terminal RF2. Connection of output contact 13/14 is only possible if the feedback contacts are closed. If output contact 13/14 is switched off, the feedback contacts must be closed 1 second afterwards, otherwise the relevant diagnostics message appears. After correction of the fault, it is necessary to perform a reset (see Chapter "Troubleshooting (Page 57)") or a restart by switching the supply voltage off and on. If contact extension or reinforcement is not used, terminals T3 and RF2 must be jumpered. Signal input P1 and P2 (position switches for protective door) P1 is supplied by test signal T1, and P2 by test signal T2. These terminals are used to connect the position switches for the protective door with a tumbler. To achieve maximum fail-safety (Performance Level e in accordance with DIN EN ISO 13849-1 and SIL3 in accordance with IEC EN 61508), the position switches are connected with two channels. The position switches are monitored for simultaneity. When the position switches are opened, contacts P1 and P2 must be opened within t < 0.5 s. If simultaneity is not satisfied, a diagnostics message appears on the display. After correction of the fault, it is necessary to perform a reset (see Chapter "Troubleshooting (Page 57)") or a restart by switching the supply voltage off and on. Both position switches must be closed to start output contact 23/24. When connecting a single-channel position switch or two individual single-channel position switches for a lower category, detection of simultaneity must be disabled in the menu. Terminals T2 and P2 must be jumpered when using a single-channel position switch. If no position switches are used, terminals T1 must be jumpered with P1, and terminals T2 with P2. If setup mode (control of terminal EA1) is selected, monitoring of the protective door contacts is deactivated (sensor circuits T1/P1 and T2/P2). The protective door can now be opened by an enabling command to the interlock magnets. 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 27 Functions 3.1 Terminals and their functions Signal input EA1 and EA2 (operating mode selection) The speed monitor is suitable for monitoring 2 operating modes (setup and automatic mode). The relevant speed limits for both operating modes are set in the menu using the pushbuttons. Safety-related selection of the operating mode, and thus the speed to be monitored, is carried out with an antivalent switch connected in a two-channel configuration to connections EA1 and EA2. Monitoring of the setup speed is selected if EA1 is connected with T1 via the antivalent selector switch, and EA2 is disconnected from T2 by the antivalent switch. To monitor automatic speed, EA1 must be disconnected from T1 by the antivalent switch, and EA2 must be connected to T2 via the antivalent selector switch. The two channels of the switch are monitored for simultaneity (tdiff < 0.5 s). If simultaneity is not satisfied, or a cross-circuit exists between EA1 and EA2, the device goes to a safe fault state. After correction of the fault, it is necessary to perform a reset (see Chapter "Troubleshooting (Page 57)") or a restart by switching the supply voltage off and on. If the 3TK2810-1 safety-related speed monitor is switched to the setup mode (control of terminal EA1), the output contact 13/14 closes immediately. If the machine speed is also within the parameterized speed window, the output contact 23/24 closes. 3TK2810-1 safety-related speed monitor 28 Manual, 05/2014, NEB926246402000/RS-AC/005 Functions 3.2 Function diagram for setup and automatic mode 3.2 Function diagram for setup and automatic mode Requirements Start type: Automatic start Protective door closed and signal present at P1 and P2 Magnet of the tumbler provides positive checkback signal (signal to MAG) Figure 3-1 Function diagram for setup and automatic mode 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 29 Functions 3.3 Function diagram for automatic mode 3.3 Function diagram for automatic mode Requirements Start type: Manual start Protective door closed and signal present at P1 and P2 Magnet of the tumbler provides positive checkback signal (signal to MAG) "AUTOMATIC MODE" is selected (no signal at EA1 and signal at EA2) 3TK2810-1 safety-related speed monitor 30 Manual, 05/2014, NEB926246402000/RS-AC/005 4 Assembling 4.1 Mounting the device on a DIN rail Requirements At the installation location, a horizontal 35 mm mounting rail in accordance with DIN EN 60715 is properly secured Please observe the information about the mounting position in Chapter "Technical data (Page 65)" DIN rail mounting procedure Step Operating instruction 1 Hang the back of the device onto the upper edge of the DIN rail 2 Press the lower half of the device against the DIN rail until the device engages Figure 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 31 Assembling 4.2 Mounting the device on a level surface 4.2 Mounting the device on a level surface Requirements Please note the following requirements for mounting on a level surface: Please observe the information about the mounting position in Chapter "Technical data (Page 65)".

If the parameterized min. setup or automatic speed is not reached within the parameterized start override time ta, the device switches immediately to the safe state. Contacts 23/24 are opened and signaling output 25 switches off. The start override executes at restart of the device, when changing from setup to automatic mode in autostart mode, and in manual start mode every time the on pushbutton is pressed. However, the requirement for this is always that before starting the start override time, all safety requirements (position switch, magnet switch, feedback circuit) must be satisfied, with the exception of the speed. During start override, output contact 23/24 is permanently connected provided the safety requirements such as position switch and magnet switch continue to be satisfied. See also Chapter "Terminals and their functions (Page 25)" in this regard. Release delay time tv The release delay time is the time that elapses until output contacts 13/14 and signaling contact 15 are switched through following a detected standstill. See also Chapter "Terminals and their functions (Page 25)" in this regard. Switch-off monitoring time tf The switch-off monitoring time is used to check the contactors connected to output contacts 23/24. If the feedback at RF1 is not available within the parameterized switch-off monitoring time tf after switching off output 23/24, a blink code in the ratio 50/50 is output at signaling output 25. An error message is also displayed. After correction of the fault, it is necessary to perform a reset (see Chapter "Troubleshooting (Page 57)") or a restart by switching the supply voltage off and on. 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 41 Operation 6.1 Times Verification of response times in the case of safety circuits When safety equipment is commissioned, steps must be taken to verify that a safety-related output will switch off within a maximum permissible response time if the input signal changes at the relevant input. To provide this verification, you must calculate the total response time of the application you have configured. Note Note that the results of calculating the response time affect the level of safety and affect the overall design of the system. Response time up to the switch-off procedure after expiry of the set start override time The maximum response time up to detection of a violation of the upper/lower limit depends on the selected parameters. The lower the set values, the longer the device requires to detect the pending fault. To achieve a faster response time, encoders or gear wheels that supply several pulses per revolution can be used (e.g. encoders with 32 pulses). This reduces the time 1 / fthreshold by the factor of the number of pulses of the encoder or the number of teeth on the gear wheel. The following applies in general: tSwitch-off_max = 1 : f + tResponse e.g. under-speed in setup mode to be checked 120 rpm = 2 Hz with initiators (1 pulse/rev.): tSwitch-off_max = 1 : 2 Hz + 150 ms = 650 ms with encoder with number of pulses = 32: tSwitch-off_max = 1 : (2 Hz x 32) + 150 ms = 166 ms f = set frequency threshold or frequency of the applied measuring signal (e.g. underfrequency in setup mode) tResponse = internal response time following detection of the switch-off frequency (max. 150 ms) Indication on the display In the normal operating mode, all set values can be checked at any time by pressing the "Up" or "Down" key. In addition, the current speed is indicated by initiator 1 or by the encoder. However, this speed does not correspond to the accuracy of the device and is used exclusively for diagnostics purposes! 3TK2810-1 safety-related speed monitor 42 Manual, 05/2014, NEB926246402000/RS-AC/005 Operation 6.2 Parameterizing/configuring 6.2 Parameterizing/configuring 6.2.1 Commissioning Note Since the commissioning and parameterization of the speed monitor are important safetyrelated steps, they must be carried out by qualified personnel.

Transmission ratio or shaft fracture monitoring In certain applications, it can be necessary to set a transmission ratio. The following arrangement of the initiators or the encoder is necessary here: The speed to be monitored on the encoder or on initiator 1 (E1) must always be greater than or equal to the speed to be monitored on initiator 2 (E2). The set speed limits on the display always refer to the encoder or to initiator 1 (E1) when a transmission ratio is set. If the gear unit switched between E1 and E2 does not have an integer ratio, it can be adjusted appropriately by modifying the resolution settings E1/E2 (pulses/rev. or mm). This arrangement is also used to detect a shaft fracture. If the measuring signals of the measuring sensor do not agree with the measuring sensor on the shaft in accordance with the ratio, the device switches immediately to a safe fault state. 3TK2810-1 safety-related speed monitor 50 Manual, 05/2014, NEB926246402000/RS-AC/005 Operation 6.3 Configuring 6.3.2 Configuration examples 6.3.2.1 Rotational motion, rotary encoder Settings on the display using the example above: Scenario A: 1.

If the fault necessitates a reset of the device, the pending fault must first be corrected and the error/diagnostics message on the device must be acknowledged. The left button must then be pressed for approximately 3 seconds to trigger a reset of the device. In the case of system faults, the device must be briefly switched off. If a system fault is detected again on switching on, the device must be returned to the manufacturer. 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 57 Diagnostics/troubleshooting 7.3 Corrective action 7.3 Corrective action Error message SF LED Error Diagnosis Device response Simultaneity of protective door not fulfilled Red Simultaneity was not fulfilled Check position switch Restart or reset Speed sensor defective Red Parameterized speed sensor does not return a signal or returns an incorrect signal * Check plug-in connection Restart or reset or terminal connection * Check signal cables * Check speed sensor Fault on external contactors (switch off) Red Device stopped and RF * contacts do not close * Check connection cables Fault in the feedback circuit (RF) Red Impermissible signal on * RF Check wiring (wire break or short-circuit) Device switches to the safe state.

When the supply returns, the device is ready for operation again. For more information on power-up please refer to Chapter "Basic versions (Page 17)", section "Power-up/self-test". 7.4.2 Internal error The device LED shows a red light in the case of an internal fault in the device. The device must be replaced and repair is not possible. Note The device LED on the 3TK2810-1 devices can also show a continuous red light if a discrepancy is found between the two internal processors that monitor each other. Apart from an actual device defect, extreme EMC influences may cause this discrepancy. If this is the case, however, the display will indicate an error code at the same time. Please notify us of this error code if the problem occurs again. With a cold start, i.e. after the control supply voltage has been interrupted, the 3TK2810-1 device forgets this error again. 7.4.3 Sensor fault 7.4.3.1 Position switch protective door When the position switches are opened, contacts P1 and P2 must be opened within t < 0.5 s. If simultaneity is not satisfied, a diagnostics message appears on the display. After correction of the fault, it is necessary to perform a reset (see Troubleshooting) or a restart by switching the supply voltage off and on. Both position switches must be closed to start output contact 23/24. If only single-channel or two individual single-channel position switches are to be connected for a lower category, detection of simultaneity must be disabled in the menu. Terminals T2 and P2 must be jumpered when using a single-channel position switch. If no position switches are used, terminals T1 must be jumpered with P1, and terminals T2 with P2. 7.4.3.2 Speed sensor If the speed sensor fails (encoder or initiators defective), the device switches to the safe state (outputs are switched off). A restart or reset is necessary following correction of the fault. 3TK2810-1 safety-related speed monitor Manual, 05/2014, NEB926246402000/RS-AC/005 59 Diagnostics/troubleshooting 7.4 Behavior in the event of a fault 7.4.4 Fault in the feedback circuit 7.4.4.1 Contacts of the feedback circuit are not closed on starting Connection of output contact 13/14 or 23/24 is only possible if the relevant feedback contact is closed. A fault message is not displayed. 7.4.4.2 Contacts of the feedback circuit do not close after stopping If the contacts of the feedback circuit do not close after the device is stopped, the contactors are still energized or defective. A message is displayed. A restart or reset is necessary following correction of the fault. 7.4.5 Cross-circuit/short-circuit If a cross-circuit or short-circuit is detected, the device switches to the safe state. An error message is generated and the diagnostics provides information on the location of the fault. A restart or reset is necessary following correction of the fault. 7.4.6 Fault in the connection to the adapter If an adapter module has been parameterized and the connection to the adapter is interrupted, or the adapter signals a fault, the device switches to the safe state. An error message is generated and the diagnostics provides information on the location of the fault. A restart or reset is necessary following correction of the fault. 7.4.7 Violation of upper/lower parameterized speed limits 7.4.7.1 Automatic speed exceeded If the parameterized maximum automatic speed is exceeded, the device switches immediately to the safe state.
